Sennheiser XSW-D Lavalier Set Description

The Sennheiser XSW-D Lavalier Set brings straightforward digital wireless operation to presenters, educators, houses of worship, corporate events, and other applications where reliable hands-free speech is required. Its 2.4GHz transmission system operates across the 2400 to 2483.5MHz range and offers a maximum operating distance of 250 ft (75 m) in optimal conditions.

The included ME2-II clip-on lavalier microphone connects to the compact XSW-D 3.5mm transmitter, allowing the speaker to move freely without holding a microphone. At the receiving end, the XSW-D male XLR receiver connects directly to a compatible mixer, powered speaker, audio interface, or other XLR-equipped device, keeping the system compact and reducing unnecessary cabling.

Built-in rechargeable lithium-ion batteries provide up to 5 hours of operation, with a typical charging time of approximately 3 hours over USB-C. The digital audio system uses the aptX Live codec and delivers an 80 Hz to 18 kHz audio frequency response through its 3.5mm/XLR signal path, a signal-to-noise ratio of at least 106 dB, and latency below 4 ms.

One-touch controls keep setup uncomplicated, while flexible transmitter and receiver pairing allows the XSW-D platform to adapt as a wireless system grows. Its lightweight components, rechargeable design, and straightforward XLR connectivity make it well suited for portable presentations, conferences, classrooms, worship facilities, event production, and installed sound systems.
